Observations were made on the morphology of floral organs inmale sterile rapes,B.chinensis L.and B.napus L..It was foundthat their floral organs were different in morphology and fertility.On the basis of morphological features,the male sterile plants couldbe classified into six types.The completely male sterile type withabortive anthers was considered of practical value and described indetail.The relation between the morphological variation of floralorgans and the degree of fertility was analysed and a few criteriafor selecting effective male steriles were suggested.These include(1)stable male sterile flowers mainly with anthers light in color ornearly necrotic and flat in shape,(2)good fertile pistils with abun-dant pod—bearing and seed—setting ability,and(3)apparently normaldevelopment of other floral parts.For selecting effective male sterilelines,the breeding methods were suggested by the author.To theauthor's opinion,the available material A_2I could be used to makehybrid rapes for breeding purpose,

对白菜型油莱(B.chinensis L)和甘蓝型油菜(B.napus L)雄性不育的花器形态进行了大量观测,结果表明:雄性不育油菜的花器存在着多种形态和育性程度的变异,初步可以分为六种花器类型。本文叙述了其中有实用价值的败药不育型的花器形态特征,分析了花器形态变异与育性的关系,提出了选育有效雄性不育油菜的花器形态指标:1.雄蕊不育性彻底稳定(以花药色浅呈坏死色泽,花药扁平即侧面无外凸增厚为主要特征。);2.雄蕊可育性好,自然结角结籽率高;3.其它花器官形态功能接近正常。对油菜有效雄性不育的选育方法也作了介绍,指出 A_2I 是选育有效雄性不育系的主要研究材料。

作者用整体解剖法,对欧州油菜花原基分化过程进行研究,发现油菜花器分化为向心分化,而与户苅义次等人提出的分化顺序不一致。作者发现的油菜各轮花器分化顺序为:花萼、花瓣、外轮雄蕊、内轮雄蕊、心皮。外轮雄蕊原基发育成短雄蕊,内轮雄蕊原基发育成长雄蕊。油菜花原基分化的实际过程并不像户苅义次等人报告的那样:雄蕊和心皮分化在花辦分化之先,甚至4枚长雄蕊是由2枚雄蕊原基分裂变来的。

A gross anatomical study of flower bud differentiation in a whole rape plant (Brassica napus L.) was made throughout its growing period. The main results obtained are summarized as follows:1. On the same plant,the higher the branch grade, the later the flower bud differentiation started.On the branches of grade No. 1 flower bud differentiation started from below upward and from above downward with the terminal node and the highest node of one third of the total nodes from the base as starting points.On...

A gross anatomical study of flower bud differentiation in a whole rape plant (Brassica napus L.) was made throughout its growing period. The main results obtained are summarized as follows:1. On the same plant,the higher the branch grade, the later the flower bud differentiation started.On the branches of grade No. 1 flower bud differentiation started from below upward and from above downward with the terminal node and the highest node of one third of the total nodes from the base as starting points.On the branches of grades No. 2-5 flower bud differentiations were basipetal.2. On the branches of grades No.land 2 flower bud differentiation proceeded at the early growing stage,at a low rate of speed and with a small quantity of floral primordia.At the elongation stage, flower bud differentiation of all branch grades proceeded, at a high rate of speed and with a large quantity of floral primordia.3. Most of the floral primordia differentiated on the main stem and its branches of grades No. land2before the elongation stage blossomed and bore fruit, whereas the floral primordia differentiated at the elongation stage scarcely bore fruit. Consequently, measures should be taken to promote flower bud differentiation at the early growing stage and check it at the elongation stage. This might be beneficial to the increase of the number of silique and thereby the raising of seed yield.

在油菜整个大田生长期间,分期镜检全株生长点的花原基分化。结果表明:茎级愈高,花芽分化开始愈迟,同一茎轴上,各分枝开始花芽分化的次序则因枝位而异。在本试验条件下,抽苔前的油菜,一、二级分枝花原基的分化速率较慢,分化数量较少,但主茎及其上部一、二级分枝在此时分化的花原基多数能开花结实。当油菜进入抽苔至开花期,各级花原基分化的速率最快,分化数量亦最多,但大多数均不能开花结实。因此,在长江下游的类似生态条件下,当油菜抽苔前适当促进花芽分化,并在抽苔期控制花芽的发生,对增加油菜产量可能具有重要的意义。
